Vibration isolation apparatuses for crystal oscillators

Abstract:

Methods, systems, and devices are described for isolating a crystal oscillator assembly from shock and/or vibration inputs. A system may include one or more vibration isolators coupled between the crystal oscillator assembly and the base structure, and each of the vibration isolators may include a spring material layer and a damping material layer. The spring material layer may provide a spring force between the crystal oscillator assembly and the base structure. The damping material layer may be adhered to at least one side of the spring material layer, and may provide a damping force between the crystal oscillator assembly and the base structure. Some vibration isolators may further include a constraint layer adhered to the damping material layer, such that the damping material layer is coupled between the constraint layer and the spring material layer.
